Page 1 of 5 RF-RR-T 24V Powered Routers/Temp Sensors Features: Benefits: Proven 802.15.4 low power network Complete range of sensor types Allows networks to be expanded Power status LED Network activity LED Technical Overview Self-healing tree topology Lower installation costs Easy to install and commission These routers are used in conjunction with the Sontay range of receiver units, and RF-RS series of battery powered sensors. They are used to route signals from battery powered nodes and other routers to the receiver module, where the signal strength of a direct path is not sufficient for reliable communications. As well as transmitting temperature values, the space versions can also be fitted with interface options. Fan speed - Momentary switch - Set-point adjust. Space and duct versions can also have a VFC input option. This can be used for any VFC device such as a pressure or current switch. It was designed with pulse counting in mind, and can be used to accept pulses from electric, gas, water or heat meters.

Page 3 of 5 How It Works: Routers are used to route signals from battery powered nodes and other routers to the receiver module, where the signal strength of a direct path is not sufficient for reliable communications. Data is transmitted back to the receiver at configurable time intervals, or on a configurable change in measured value. Each sensor retains these configurations if the battery becomes discharged or requires replacement. The sensors, routers and receiver automatically select which of the 16 transmission channels available gives the best radio network performance, taking into account both signal strength and interference levels from adjacent channels and equipment (such as Wi-Fi etc.) The sensors and routers automatically find the best path back to the receiver, which may be NB Each router can support a maxi and a maximum of which can be 8 routers. Consideration should be given on network planning for redundancy in case of router failure or damage. Aerial Orientation (plant sensor types); For best results ensure that the main body of the aerial is vertical. Installation: Plant Sensor types: 1. Remove all packaging from the sensor. 2. Note the MAC address printed on the affixed label and note where this MAC address is installed. 3. Mount the sensor in the required position (this will have been determined by the site survey tool, (see the quick start guide and manual). 4. It is recommended that the unit be mounted with the cable entry at the bottom. If the cable is fed from above then into the cable gland at the bottom, it is recommended that a rain loop be placed in the cable before entry into the sensor.
Centers MountingScrew RF-RR-T Page 4 of 5 Installation (continued): 5. See below for individual installation depending on sensor type. 6. Release the snap-fit lid by gently squeezing the locking tab and feed the cable through the waterproof gland & terminate the cores at the terminal block. Leaving some slack inside the unit, tighten the cable gland onto the cable to ensure water tightness. 7. Observe correct polarity if using a 24Vdc power supply. To power on the unit, fit J200. 8. Snap shut the lid after the connections have been made if IP65 protection is required, secure the lid with two screws provided. 9. Ensure, at a minimum, that all routers and the receiver on the radio network are powered on, and allow about 5 minutes for the network to auto-commission before attempting to read values or make configuration changes. Duct Select a location in the duct where the sensor probe will give a representative sample of the prevailing air condition. Drill a 7mm diameter hole in the duct, then use the housing as a template mark the hole centres or use the dimensions below), drill and fix the housing to the duct with the screws supplied. 24 mm 33 mm Ø7 mm Immersion Select a location in the system where the liquid is to be measured, install pocket as per datasheet TT-PO. Insert the probe into the pocket and secure with the grub screw provided within the pocket. The immersion sensor must be used with a pocket; it is not designed for direct mounting. Clamp-on Select a location in the system where the liquid temperature is to be measured, where the brass lug will make good contact with the surface of the pipe. Secure the brass lug to the surface to the pipe using the clip provided. Wrap the clip around the pipe and place the lug under the strap and tighten the clip. It is good practice to ensure that good contact is made between the lug and the pipe, and apply insulation over the pipe and lug. Outside air Select a suitable location preferably on a north facing wall, ensuring that the sensor is away from direct sunlight and any heat sources. Outside air with radiation shield Select a suitable location, the sensor has a radiation shield that helps minimizes error gains from direct sunlight.

Mount the sensor in the required position (this will have been determined by the site survey tool, (see the quick start guide and manual). 3. Undo the tamperproof screw at the bottom of the housing and gently pull the front panel from the base. 4. Using the base as a template mark the hole centres and fix to the wall with suitable screws. Alternatively the base plate can be mounted on to a conduit box or a standard recessed back box. 5. Feed cable through the 22mm knockout in the base of the housing and terminate the cores at the terminal block as required. Leaving some slack inside the unit. 6. Observe correct polarity if using a 24Vdc power supply. To power on the unit, fit J200. Replace the housing to the base plate then re-fit the tamperproof screw through the lug at the bottom of the base plate. 7. Ensure, at a minimum, that all routers and the receiver on the radio network are powered on, and allow about 5 minutes for the network to auto-commission before attempting to read values or make configuration changes. Options: Fan Speed Switch Each time a change of position is detected it is transmitted immediately. Momentary Switch it is transmitted immediately and the current output status is inverted (TRUE goes to FAUSE or FAUSE goes to TRUE) and stays in the new state until the switch is pressed again. Set-point Adjust When the rotary dial when moved in any direction, it is transmitted immediately. VFC Used for any VFC digital input (such as a pressure switch or current switch), but it has also been designed with pulse counting in mind. It TRUE inputs is counted by the router or ED, and held in flash memory, so even if the ED or router doing the counting goes ing strategy to be updates when the ED or router comes back online meaning a pulse will never be missed. The ED or router can hold the number of VFC TRUE conditions up to 4096, and is user resettable if required Whilst every effort has been made to ensure the accuracy of this specification, Sontay cannot accept responsibility for damage, injury, loss or expense from errors or omissions. In the interest of technical improvement, this specification may be altered without notice.
